Answer:
Pleurisy.
Explanation:
Pleural membranes are two membranes which surround our visceral organ named as lungs and protect them. Between these two membranes, fluid is filled which acts as a lubricant and reduces friction. It is because of this plural fluid that the two membranes are able to slide easily during respiratory movement. But in case plural fluid fails to prevent friction it leads to pain and inflammation and this diseased state is known as Pleurisy.
